Training to eventually track.

Hi, im posting to see if anyone has any tips on training dogs to eventually track deer etc.

My dog is a black Labrador retriever and is about 15 months old or so. She listens good already and the training I've been doing to get her to follow basic instructions has worked very well so far. I was wondering if anyone has some tips to help make this a smooth and effective process or has any suggestions on what to avoid doing. Thank you!
